KNOCKDOWN BED.

Application filed April 30, 192 1. Serial No. 710,008.

lily present invention relates to a knockdown or folding bed capable of being compacted nto a comparatively small space,

this bed being of the same general type as,

and improvement upon, that described and legs; and it is an object of claimed in my co-pending application Serial No. 620,158, entitled as relating to Demourtable camp beds, and filed February 20, 1923.

As in the mentioned application, and as in cot beds generally, my knockdown bed may consist essentially of a spring or fabric element, a frame comprising side members and end members to which said spring or fabric element is secured, and supporting this invention to and effective means enabling side members to be satisfac and enabling the same to be reliably connected at will to end members to which the mentioned legs are pivoted in such manner that any weight 'upon a cot or bed of my improved design must tend to lock or bind the said side members securely in place.

It is an object of this invention to provide a simple cot construction comprising end frame members to which legs may be pivotally connected in a manner enabling them to act as levers in the retention of side members, said side members being entirely movable and separately foldable to a length permitting the same to be conveniently disposed within a vehicle or upon a pack animal, the tops of the mentioned legs being so spaced from the substantially horizontal elements of the mentioned end members as to permit of the insertion of the slotted ends of side members therebetween, and the ex tension of said side members being preferably effective to tension said spring.

It is a further object of one embodiment of this invention to provide means permitting the optional use of a removable head or pillow rest of a specific type hereinafter described.

Other objects of my invention will appear from the following description of an advantageous embodiment thereof taken in con nection with the appended claims and the accompanying drawings, in which Fig. 1 is a perspective view of a typical embodiment of my present invention.

Fig. 7 is a view of the end of one of the side members showing the slot formed therein and s iowing a strut member pivoted thereto.

Fig. 8 is a fragmentary planview showing members for supporting a pillow rest.

Figs. 9 and 10 are views showing the pillow rest which may be employed with the supporting means shown in Fig. 8.

As shown in Fig. 1 of the drawings, my invention may comprise end members 11 to which legs 12 are pivoted near the ends thereof, as shown at 13. As shown in Figs. 2 and 3, end struts 14 may be pivoted as at 17, to the vertical flanges 16 of the end members 11, and the free ends thereof may be provided with pins 18 arranged to be removably extended into holes 19 in the legs 12. Side members 21 extend between the end members 11 and may be of such length as to place the spring fabric 22 under tension, assuming the spring fabric 22'to be secured between the end members 11. The ends of the side members 21, as shown in Fig. 7, are provided with slots 241, which are shown in Fig. 3 s0 spaced that pins 25, secured in the flanges 26 ofthe end members 11, pass therethrough. The ends of the side members 21 may abut against the vertical flanges of the end members and be held thereagainst by the tension on the fabric 22. As shown in Figs. tand 5, side members 21 may be hinged so that they may be folded into a length which may be substan tially that of the end members 11. A hinged and somewhat resilient strap 28 is shown as rigidly secured to a section 29 of the side member 21 by means of rivets 30, and as pivoted at its other end to a section 31 by means of a single rivet 32. In order to prevent lateral movement between the sections 29 and 31, a pin 33 is provided, which retains the bar 28 securely against the wall 34 of the member 31. The ends of the bars 29 and 31 are arranged to abut as indicated at 36. Pivoted at 37, as shown in Fig. 1, to the side members 21, I may employ struts or braces 39, which are arrangedto be secured to the legs 12 in the same manner as the end struts or braces 14:. As shown in Fig. 2, the end struts 14 are of such a length as to permit the leg members to move slightly beyond the vertical plane indicated at AA. That is, the lower ends of the legs 12 are farther apart than the top ends thereof; and from this it will be seen that when a weight is placed upon the bed, there will be a tendency for the lower ends of the legs to swing outwardly as indicated by the arrow in Fig. 2, so that, the legs acting as levers, the upper ends 41 of the legs will be caused to engage the horizontal flange 29 of the side members 21 and grip them rigidly in place. In this manner I may provide very simple means for making rigid connection between the end members 11 and the side members 21.

The bed may be disassembled in the following manner: The end struts 1d may be first disengaged from the leg members 12, as shown in Fig. 2, and allowed to swing into position as indicated at 13. The struts let may then be swung into position as indicated at 4A in Fig. 4c, and the pin 18 thereof may be placed in a hole 45 and in that manner be retained along the end frame 11. The side struts 39 are similarly removed from place and may assume positions as indicated by the dotted line 17 in Fig. 1. If the legs 12 are then swung to or within the vertical position as indicated by the dotted lines i8 of Fig. 2, it will be seen that this disengages ,the contact between the upper end 11 and the flange 29 of the side member 21 permitting the latter to be withdrawn. The side members may then be folded, as inclicated by the dotted line of Fig. 5, to permit removing the side members from place by reducing tension on the fabric 22. The end members may then be pulled outwardly against the tension on the fabric 28, in a manner to remove the pins 25 from the slots 24. It will be seen that in order for the side members comprising sections 29, 31 to be compactly folded, it is necessary for the member 29 to be moved or sprung laterally, somewhat as shown by the dotted lines 50. This is compensated for by the flection, as indicated at 51 in the hinge bar or strap 28. Before or after the described move ments, leg members 12 of the end frames 11 may be swung as indicated at 52 in Fig. 4E. The end frames, the fabric, and the side members may then be rolled into a' very compact bundle suitable'to be secured to, for example, the running board of an automobile. i

If desired, my camp bed may also be provided with a head rest 60, as shown in Figs. 10 and 11. This head rest may optionally be made as an integral casting and it may com-1 P is erticl f Pos i j d s ef i horizontalrods 62. In the'eye'nt of the utiliaati'on of this head frame it will be vdicated above and necessary to provide for attaching the same, as by supporting lugs 63, which may be very suitably secured by means of rivets 64L to one of the end frames 11. Openings 65 are shown as provided in each of the lugs 63, through which the reduced cylindrical portions '56. formed on the lower end of the post (31, may extend.

From the foregoing description it will be readily perceived that a bed of this type is suitable for extensive use, as in camping trips, because of the simple construction thereof, because of the sleeping comfort it provides, because of the rigidity thereof when assembled, because of the ease with which it may be assembled or disassembled and because of the compactness thereof when disassembled.

Although Ihave herein described a preferred embodiment of my invention, it will be understood that various features thereof might be independently employed, and also that various additional modifications might be devised by those skilled in this art, without of the slightest departure from the spirit and scope of my invention, as the same is iniii the following claims.

I claim as my invention:

1. in a knock-down bed, a pair of end members each having a flanged portion and a pair of legs so pivoted thereto as to leave a space between said legs and said flanged portion for the insertion and locking of the ends of removable site members therebetween, and a pair of side members insertable in said space and provided with means for their secure retention against lateral displacement, said retaining means compris- .ing slots in said ends to receive pins projecting downwardly from the flanged portion of said end members.

2. In a knock-down bed: an end member having a vertical wall and a horizontal upper flange; a pair of legs each pivoted at its upper end to said vertical wall below said flange to provide an intermediate space; and removable side members each insertable in one of said. intermediate spaces and adapted to be clamped against said flange by the adjacent leg.

3. In a lmocl clown bed: an end member comprising a transverse angle iron provid ing a vertical wall and a horizontal flange ext-ending inwardly; and a pair of legs pivoted at their upper ends respectively opposite. end portions of said vertical wall sutiiciently below said horizontal flange to leave an intermediate space between said flange and each leg to receive the end of a side member; longitudinal side members insertable respectively in said spaces; means for retaining the side: members against lateral displacement, said legs being operable to clamp said side members a'gainst'theflange of said endmeinber, said retaining 'means.

comprising cooperating slots and projections respectively associated with the end member and the side members.

4;. In a knock-down bed comprising side members formed of angle-iron sections, joints in said side members comprising straps rigidly secured to one of said sections, and pivoted to another of said sections, each st zip and associated parts being sufliciently resilient to permit said sections to be either positioned end to end or folded one Within another.

5. In a knock-down bed comprising side members formed of angle-iron sections,

joints in said side members comprising straps rigidly secured to one of said sections and pivoted to another of said sections, each strap and associated parts being sufficiently resilient to permit said sections to be either positioned end to end or folded one within another, one of said sections being provided with means so engaging a strap pivoted thereto as to force a pair of said sections into substantial alignment.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 23rd day of April, 1924.
